NetBSD is not (yet?) a real-time OS; FIFO_TRIGGER_14 is excessively
optimistic.
One approach would be to "adaptively" set the FIFO trigger interval...
when you get a "silo overflow", drop the trigger to the next lower
threshold. You could reset the interval to _14 every time you drop
the baud rate.
